Terrain on the street pretty level

I plan on addiing a 400amp controller since I will be adding 2 rear seats. I am also going to add a heavy duty solenoid and 4 gauge wires all the way to the motor and inbetween batteries. hoep to get a little more juice on top.

Anybody have sugestions on what soleoid to get or where to get a good deal on some 4 gauge battery cables.
